摘要 利用大型有限元软件ANSYS/LS-DYNA,对钢框架焊接节点在爆炸荷载作用下的动力响应进行了数值模拟,通过分析节点区位移时程曲线,得出节点在不同爆炸荷载作用下的动力响应特性,指出在爆炸荷载作用下,框架节点端部位移快速达到最大值,而后振动恢复至平衡位置,爆炸峰值压力越大,节点区梁柱最大位移和残余位移越大。 The ANSYS / LS-DYNA software is used to set up the steel frame joints models and analyze the responses subjected to blast loads. The dynamic response characteristics of joints under different blast loads were obtained through analysis of displacement time history curves of joints.The paper points out that under blast loads,the joints displacement quickly reach the maximum value,and then decrease to the equilibrium position. The displacement maximum value and residual displacement of column and beam increase with the increase of blast loads.
